Product Overview
Cerium(III) nitrate hydrate from REacton™ delivers exceptional 99.998% purity on a metals basis, making it a premium choice for applications demanding ultra-low impurity levels. This hydrated crystalline powder exhibits excellent solubility in water and polar solvents, ensuring uniform dispersion in reaction media. The compound’s high cerium content and minimal trace metal contamination make it particularly valuable for catalysis, where it serves as a Lewis acid or oxidation catalyst in organic synthesis. Its controlled hydration state provides stability during storage while maintaining reactivity when required. The REacton™ grade undergoes rigorous quality control to eliminate common contaminants like iron, calcium, and heavy metals, which could interfere with sensitive analytical techniques. The powder’s fine particle size distribution enhances dissolution rates, reducing preparation time for experimental setups. Compatible with most laboratory glassware and standard filtration systems, this cerium nitrate variant avoids the agglomeration issues often seen in lower-grade alternatives. Its neutral pH in solution prevents unwanted side reactions in pH-sensitive processes. The product’s sealed packaging with moisture barriers preserves its hydrated form during transit and storage, while the 100g and 25g pack sizes offer flexibility for both large-scale synthesis and small-batch experimentation.
FAQs
1. What is the exact hydration level of this cerium nitrate?
The product typically contains 6 moles of water per mole of cerium nitrate (Ce(NO₃)₃·6H₂O), though the exact hydration may vary slightly due to handling conditions. The 99.998% purity specification refers to the metals basis, excluding water content.
2. Can this be used directly in non-aqueous solvents?
While primarily water-soluble, the hydrated form shows limited solubility in alcohols like ethanol or methanol. For non-aqueous applications, consider dehydrating the compound under controlled conditions or using anhydrous cerium nitrate alternatives where absolute moisture exclusion is critical.
3. What’s the difference between REacton™ grade and standard lab-grade cerium nitrate?
REacton™ grade undergoes additional purification steps to achieve 99.998% metals basis purity, with stricter controls on trace elements like iron (typically <5 ppm) and heavy metals (<1 ppm total). Standard lab grades often contain 99.5-99.9% purity with higher impurity thresholds, which may affect catalytic performance.
4. How should I store this to prevent moisture absorption?
Store the unopened container in a cool, dry place (15-25°C) with the original desiccant pack. After opening, transfer unused portions to an airtight container with fresh desiccant and purge with nitrogen if long-term storage is needed. Avoid vacuum sealing, as this may alter the hydration state.
5. Is this compatible with PTFE or polypropylene labware?
Yes, the compound is chemically inert toward PTFE and polypropylene under normal lab conditions. However, prolonged contact with concentrated solutions (>1M) at elevated temperatures (>60°C) may cause minor surface etching in polypropylene. PTFE remains fully compatible across all conditions.
